Harmonic Highlights:

  • Frequent use of secondary dominants (B7 to C, E7 to Am7) extending harmonic movement beyond simple diatonic progressions.
  • The Ab07 chord functions as a chromatic diminished approach, creating tension and leading into the ii chord (Am7) non-diatonically.
  • Relies on the foundational ii-V-I progression (Am7-D7-Gmaj7) as a core building block for diatonic resolution.

Improvisation Focus: Navigating secondary dominants and chromatic approaches by identifying their temporary target tonalities.

Difficulty Rating: 3/5. The blend of standard ii-V-I progressions with common secondary dominants and a chromatic diminished chord presents a moderate challenge.
